At about 8:30 p.m., King County deputies responded to a 911 call about a shooting in the 26500 block of 233rd Avenue SE, according to Det. Jason Stanley with the King County Sheriff's Office.
While en route to the house, Stanley said deputies got word of a 30-year-old man being dropped off at a nearby 7/11 convenience store with a gunshot wound to the face.
Deputies responded to the 7/11 and found the injured man, who was taken to Harborview Medical Center.
While speaking to the injured man, deputies learned a woman had just checked herself in at Valley Medical Center with at least one gunshot wound.
Stanley said it appears both people were shot at the house on 233rd, but he doesn't yet know how the shooting unfolded.
"We don't know for sure yet if it was a burglary, robbery, fight among friends. We don't know yet," he said.
While driving from the house to the 7/11, Stanley said either the wounded man or the wounded woman tossed several guns out the window of their car.
Deputies have since recovered three shotguns and assault rifles from the roadside.
"It's very strange," Stanley said. "We haven't pieced it all together yet. We haven't had two people tell us the same story and it's still very early in the investigation."
Stanley said nobody had been arrested and detectives are still trying to figure out exactly what happened.
"We don't have anyone in custody right now," he said. "We don't know who's a suspect and who's a victim in this situation."
